全(重整化)全息作用量的计算是在一般的爱因斯坦标量理论中进行的。发展了相应的形式，并计算了度规算符和标量算符的二阶导数的重整化有效作用量。全息RG方程包括时空度规的广义Ricci流和标量算符的标准β函数流。对几个算例进行了分析，并计算了有效作用。发现了一组全息流的守恒量，但其解释尚不清楚。
The calculation of the full (renormalized) holographic action is undertaken in general Einstein‐scalar theories. The appropriate formalism is developed and the renormalized effective action is calculated up to two derivatives in the metric and scalar operators. The holographic RG equations involve a generalized Ricci flow for the space‐time metric as well as the standard β‐function flow for scalar operators. Several examples are analyzed and the effective action is calculated. A set of conserved quantities of the holographic flow is found, whose interpretation is not yet understood.
